More than likely its a random price due to it being a "have to order part" and the actual cost is unknown.

Well usually OEM Mercruiser costs more than anything from Sierra. I needed a regulator bc mine was orig and had issue with crumbling insulation on the wires. Not burnt or touching anything they shouldn't mind you but old age (1988). The diode went bad but the alternator tested just fine. Getting it rebuilt anyway at an independant alt/starter rebuild shop called Sure Power in Jackson Ga. They told me they can rebuild a marine alternator. They did a great job on our '59 Apache 1wire alternator a few years back.

Thank you Edchris177 for posting the requested Link !
